Turnover at the U.S. Mission to the OAS Amid Ambassador Leandro Rizzuto Jr.’s Management

Turnover
In June 2026, the U.S. mission to the Organization of American States (OAS) lost its deputy chief of mission, chief of staff, senior political counselor and at least one other foreign-service officer, emptying the senior leadership of a mission that normally has only a few career diplomats. The OAS, founded in 1948, is the Western Hemisphere’s main forum for security, human rights, democracy and economic development. The departures coincide with a Trump-era reshaping of the State Department, which has expressed skepticism toward multilateral bodies and large-scale layoffs.
Key Figures
Leandro Rizzuto Jr., a friend of President Donald Trump and heir to a cosmetics fortune, was confirmed as U.S. ambassador to the OAS in late 2025 after a failed Caribbean nomination and a Senate-free posting to Bermuda. The departing staff were foreign-service officers whose names were not disclosed.
Staff Changes
At least four officials left, representing most of the mission’s leadership. The State Department reported that several hundred officers were dismissed in layoffs the previous year and that nearly 30 career ambassadors were removed in December, leaving many posts vacant.
Official Statements
Rizzuto said the mission is being refocused on economic issues and that those who left have been succeeded by high-performing staff. He described himself as “the fairest guy” and emphasized a business-oriented approach to results. State Department declined to comment on questions about the changes.
Criticism
Sources described Rizzuto’s style as confrontational and erratic, noting he once called staff who raised concerns “rats.” Critics argue the turnover erodes institutional expertise and that Trump-era reforms have harmed career public servants. The same sources disputed the implication that departing staff were incompetent.

- “I'm a business guy, so the bottom line is I want results, and without making it personal, if you can't do the job, I'd rather you have another job,” — Leandro Rizzuto Jr., OAS ambassador

Conflicts
Rizzuto said he forced out his deputy chief of mission and chief of staff, while other accounts describe those officials as having resigned or been fired. He claims replacements are high-performing, yet the departures removed the entire leadership, leaving uncertainty about continuity. No independent verification of the new appointees’ performance is available.
What’s Next
Trump officials have floated reforms to make the OAS more relevant, proposing a role in hemispheric security and law-enforcement cooperation. Rizzuto’s shift toward economic priorities suggests a reorientation of U.S. engagement, but the effect of the staffing upheaval on policy implementation remains unclear.
